The 10 common geographical phenomena in life are:
1. The phenomenon of day and night alternation. The earth is rotating all the time, because the rotation of the earth has a day and night.
2. Heavy fog for three days, there will be heavy rain. Heavy fog refers to heavy fog, which lasts for three days, indicating that the warm and humid airflow is particularly strong. The stronger the warm and humid airflow, the heavier the rain will fall when the cold air arrives.
Therefore, the proverb that there will be heavy rain on three days of heavy fog is relatively accurate, regardless of the season.
3. Spicy food in Chongqing. The reason is that the climate in the southwest is humid, and the peppers can go to the tide.
4. The phenomenon of red tides is not the blood covering the ocean, but the algae and plankton, which are so numerous that they fill the waters. In some cases, the water is dyed bright red by the aggregation of tiny organisms, and some red tides are harmless, but some, such as toxic substances from the China Sea, can be harmful to marine life.
5. Rainbow and neon contain seven colors of sunlight, water droplets (raindrops or fog drops) into the atmosphere, and various colors of light can form a colored arc ring on the rain curtain or fog curtain after refraction and reflection.
6. "It's cold early, it's warm early". If the coldest period is significantly earlier, it is often less likely to be cold of the same magnitude in the same winter, indicating that the season will be earlier and spring may come sooner.
7. In the hot summer, the temperature in the green space with good greening condition is 3-5 degrees lower than the temperature in the area without greening, such as we measure the temperature difference between the green space and the non-green space in the residential area as degrees.
8. Hail is common in the warm season, and it is formed in vigorous cumulonimbus clouds. There are many reasons for the formation of cumulonimbus clouds, one of the most important of which is the strong air convection in summer.
9. During the hot summer months, forests can help lower temperatures. The forest is like a large "parasol", and under the shade of the canopy, the woodland receives very little direct solar radiation and the ground warms very little. At the same time, the water content of the woodland is relatively high, the specific heat capacity of the soil is larger, and the warming of the ground is smaller than that of the wilderness.
10. Heavy fog refers to heavy fog. The fog lasted for three days, indicating that the warm and humid airflow was particularly strong. The stronger the warm and humid airflow, the heavier the rain will fall when the cold air arrives. Therefore, the proverb that there will be heavy rain on three days of heavy fog is relatively accurate, regardless of the season.

Geographical phenomena include: desert areas bordering the ocean, oases on the "return to the desert zone", hot centers at "higher" latitudes, equatorial snow-capped mountains, polar circle gardens, enclaves, and large fishing grounds where cold and warm currents meet. The details are as follows:
1.A desert area bordering the ocean.
The ocean is the source of water vapor and the home of clouds and rain. The coastal areas of the mainland are generally greatly affected by the ocean, and the precipitation is relatively abundant, and most of them belong to the humid climate. However, desert environments have developed on the west coast of Australia, the Pacific coast of Peru, and other areas.
Because it is controlled by the subtropical high pressure zone all year round, downdrafts prevail, and the air warms and dries. At the same time, prevailing winds blow from the land to the ocean, and there is little water vapor, making it difficult for clouds and rain to form. In addition, cold currents pass through the coastal oceans, which reduce cooling and humidification, further exacerbating the aridity of the climate, extending the desert area to the coast. The most typical of these are the northern Chilean and Peruvian coastal regions of South America, which are not only the least precipitation and the driest climate in the world, but also the desert area that extends north to the equator with the strong Peruvian cold current, becoming a natural wonder.
2.An oasis on the "Return to the Desert Belt".
The area near the Tropic of Cancer on the earth has an arid climate because it is controlled by the subtropical high pressure zone or the trade wind belt, where tropical continental air masses prevail, with low precipitation and high evaporation. Most of the world's deserts are distributed here, so it is called the "return desert zone".
3.Hot centers at higher latitudes.
In the northern and southern hemispheres, temperatures decrease from low latitudes to the poles in both July and January. Generally, the temperature is high in low latitudes and low in high latitudes. However, the hottest place in the world in July is not at the equator, but in the desert areas of the continent between 20° and 30°N, and the Sahara Desert is the hot center of the world.
The average temperature here in July is mostly above 30, and Azizia, Libya, has an absolute highest temperature of 58, which is the world's famous "hot pole".
4.There is no large fishing ground where cold and warm currents meet.
In the sea area where cold and warm currents meet, plankton growth and reproduction are particularly rapid, and fish bait is abundant. At the same time, both warm-water and cold-water fish are stranded there, so the fishery resources are abundant. Almost all of the world's major fishing grounds are located in these areas. For example, the Newfoundland fishery in the Atlantic Ocean, the Hokkaido fishery in Japan, and the Zhoushan fishery in China, etc.

Stone Flow,MudslidesIt often occurs in canyon areas and **volcanic areas, and has ** nature during heavy rainfall. Hurricanes, hurricanes, also known as typhoonsTornado, formed near the equatorial oceanTropical cyclones
Lingxun, commonly known as ice row.
It is a hydrological phenomenon caused by the resistance of ice to the water flow. The seaside is cooler than the land in the summer, and the seaside is warmer than the land in the winter, the reason is the difference in the heat of the sea and the land.
Floods, flood-inducing factors are extremely widespread, such as flooding, storms, volcanic eruptions.
Tsunamis and the like can cause flooding, and even man-made ones can cause flooding.
In the past, when science was not developed, people often explained the reasons for their occurrence with the help of the power of the gods. Volcanoes, craters are cracks in the earth that release heat and gas.
The diurnal phenomenon, the Earth is a non-luminous, opaque sphere, and at the same time, the Sun can only illuminate half of the Earth's surface. Every day the sun always rises in the east and sets in the west, because the earth rotates from west to east, so people on the earth seem to have the sun coming out of the east. The climate of the south and north of the mountain is different, the reason, the influence of the topography on the climate.
Cloud
A cloud is a type of cloud that is not classified as a cloud in meteorology. International research is still superficial, and there is still no common view. Now the Western and Japanese academic circles have an untrustworthy and pseudo-scientific attitude towards **cloud, after all, the movement of the earth's crust has not yet been found.
Theoretical evidence associated with short-term meteorological changes.
If the light comes from the outside, I have to say that it is a very beautiful cloud. Brief description of the principle: **When it is about to happen, it is gathered in the **zone.
Or because the rock in the ** zone is subjected to strong stress, a large amount of heat is generated due to intense friction. This heat escapes from the surface of the earth, warming the air to produce an updraft, which forms a "cloud" at high altitude, and the tail end of the cloud points to the place where it occurs.

1. Aurora. The aurora is a collaboration between the sun and the atmosphere. Among the forms of energy created by the sun, such as light and heat, there is one type of energy known as the "solar wind".
The solar wind is the charged particles ejected by the sun, a powerful stream of charged subatomic particles that can cover the earth. The solar wind flows around the Earth above the Earth, hitting the Earth's magnetic field at a speed of about 400 kilometers per second. The Earth's magnetic field is shaped like a funnel, with the tip facing the north and south poles of the Earth, so the charged particles emitted by the Sun settle along the "funnel" of the Earth's magnetic field and enter the polar regions of the Earth.
The upper atmosphere of the poles glows when bombarded by the solar wind, forming auroras. The formation in the Antarctic region is called the Australis Aurora. The Northern Lights that are formed in the Arctic region are called the Northern Lights.
2. Polar day and polar night.
It is caused by the rotation of the earth around its own inclined axis as it revolves around the sun in an elliptical orbit. It turns out that when the earth rotates, the earth's axis and its perpendicular line form an approximate inclination angle, so when the earth rotates, there is always one of the poles facing the sun for 6 months, and it is all daytime; The other pole is turned away from the sun, and it is all night. The North and South Poles are amazing natural phenomena that no other continent has.
3. Warm current. The water temperature is higher than that of the surrounding seawater, which usually flows from low latitude to high latitude, and the water temperature gradually decreases along the way, which has a warming and humidifying effect on the climate along the way. It also describes people's psychological feelings
4. Plate movement.
5. Volcanic eruptions.

Temperature, climate, topography, geology, etc., are affected by the regional environment.
Our country is from south to north. The latitude gradually increases, and the temperature gradually decreases. Hainan Island in the south has long summers and no winters, and Heilongjiang in the north has long winters and short summers.
From the southeast coast to the northwest inland, the farther and farther from the sea is getting farther and farther away, and the precipitation is getting less and less. The southeast coastal area is humid and has beautiful mountains and rivers; The northwest inland region is arid, and deserts and Gobi are widespread. From west to east, China's topography is distributed in a stepped manner, declining step by step.
China has a vast territory, a complex and diverse natural environment, and a variety of human phenomena.
